Study On Methods Of Momentum Matching Pipeline Network In Heating And Air-conditioning Engineering

In HVAC, there are water and wind system. The water pump and fan's using is driving flux circular flow, and the need of heating and cooling. The using of valve is increase resistance to consume superfluous segmental compressive stress. The valve energy sources expending are more, the regulation is good, so want to achieve good regulation effect will consume more water pump and fan energy sources expending. Using distributed alterable- rapidity water pump and fan supersede fun valve and water valve will economize prodigious inverse proportion energy sources expending. This quomodo has important meaning of saving energy sources. How to matching–momentum well, and what theoretic in it, these are main matter in this article.First this article use water compressive stress fig to analyze water compressive stress. Then from pipeline network's basic model, analyze unattached loop press balanceable equation's matrix, and uncoil the matrix. Sum up the best matching–momentum theoretics. Its include the list energy sources expending of pipeline network, the mode of list dynamic equipment and so on. give an example with some pipeline network, using"analyze software of loop pipeline network hydraulic count and hydraulic work status"to emulational simulate. We can know using method of list energy sources expending can save about 28% than traditional method.Then compare the choose of press point in these pipeline network control method, analyze measures of these control method, we can know use invariableness difference of supply and return press. Keep it is zero. Its effect is best. And compositive evaluate to the four typical and traditional method, we can know the best matching–momentum method is matching–momentum at heat fountain adding branch of pipeline networkAs a result of there are many branch of pipeline network, the best matching–momentum method is a large number. For frondose pipeline network there is many place to setting equipment. It is also can realize the list energy sources expending, at the same time it easy to operation and control.At last, give an example with underground pipeline of the RC hospital. Simulation data indicate this best matching–momentum theoretics can resolve water power problem very well and its effect of saving energy sources is more prominent.
